| leg of antihelix | One of two ridges, inferior and superior, bounding the fossa triangularis, by which the antihelix begins at the upper part of the auricle. Synonym: crus anthelicis, leg of antihelix. (05 Mar 2000) |
| leg phenomenon | In tetany, spasm both of the extensor muscles of the knee and of the calf muscles when the extended leg is flexed at the hip. Synonym: leg phenomenon, Pool-Schlesinger sign, Schlesinger's sign. In tetany, contraction of the arm muscles following the stretching of the brachial plexus by elevation of the arm above the head with the forearm extended, resembles the contraction resulting from stimulation of the ulnar nerve. Synonym: arm phenomenon. (05 Mar 2000) |
| leg ulcer | Ulceration of the skin and underlying structures of the lower extremity. About 90% of the cases are due to venous insufficiency (varicose ulcer), 5% to arterial disease, and the remaining 5% to other causes. (12 Dec 1998) |
| lip and leg ulceration | An infectious disease of sheep characterised by crusted ulcers on the skin of the face, feet, and external genitalia; thought to be caused by the orf virus. Synonym: lip and leg ulceration. (05 Mar 2000) |

| aortopulmonary septum | The spiral septum which, during development, separates the truncus arteriosus into a ventral pulmonary trunk and dorsal aorta. See: bulbar ridge. (05 Mar 2000) |
| atrial septum | The wall between the two upper chambers (the right and left atrium) of the heart. (12 Dec 1998) |
| atrioventricular septum | The small part of the membranous septum of the heart just above the septal cusp of the tricuspid valve that separates the right atrium from the left ventricle. Synonym: septum atrioventriculare, pars membranacea septi atriorum. (05 Mar 2000) |
| Bigelow's septum | A bony spur springing from the underside of the neck of the femur above and anterior to the lesser trochanter, adding to the strength of this part of the bone. Synonym: Bigelow's septum. (05 Mar 2000) |
